ValidateImpexAction doesn't use configured hostname

[bjmi]

The default hostname string "http://localhost:9001/hac" is always used for validation action and not the configured url in preference page.
In
ValidateImpexAction

final String hostName = store.getDefaultString(PreferenceConstants.P_HOST_ENDPOINT_STRING);
should be replaced with
String hostName = store.getString(PreferenceConstants.P_HOST_ENDPOINT_STRING);

Please also rename the label "Host name:" to "URL to HAC:" or something that better express that it must be a URL.
